Abstract
The utility model relates to an air flow guiding device, in particular to a fan air flow tower air flow guiding device, which mainly solves the technological problem of loud air-out noise in an exhaust passage, the air flow's pouring in the fan backwardly and the rain water corrosion in existing technology. Technical project of the utility model is a fan air flow tower air flow guiding device, wherein a plurality of folded diversion separators are equipped inside the exhaust passage of the air flow tower silencer outlet, folded diversion separators are built up by a downward flow guiding panel and an upward flow guiding panel wherein the length of the downward flow guiding panel is two to three times of that of the upward flow guiding panel, alpha angle between the downward flow guiding panel and the horizon is thirty five to fifty degree, beta angle between the downward flow guiding panel and the upward flow guiding panel is ninety to one hundred degree, the distance between the folded diversion separators is forty five to sixty mm, the horizontal length of the downward flow guiding panel is two thirds of the depth of the gas exhaust passage. The utility model is mainly used for the gas guidance on the air flow tower air outlet of an air blower.
Description
Technical field: the utility model relates to a kind of airflow guiding device, particularly a kind of blower fan tower airflow guiding device that leaks informaton.
Background technology: in Blast Furnace Blower System, all be provided with the tower sound arrester that leaks informaton, its purpose is under the situations such as blast furnace staying, the adjusting of blast furnace special operation condition, accidental state, the operation of leaking informaton, the high temperature and high speed air-flow that blower export leaks informaton is directly discharged through the tower sound damper passage that leaks informaton.Leak informaton tower and blower fan air intake filtration unit homonymy, close together, tower sound damper exhaust-duct is a bypass structure because blower fan leaks informaton, the hot blast that causes part to be discharged, under the blower inlet suction function, reenter gas blower, cause gas blower inlet side temperature to raise, cause the problem that blower efficiency descends and primover (steam turbine or motor) power consumption increases; In addition, because the structure of not keeping off the rain, cause rainwater to enter to leak informaton the tower sound damper to cause inner corrosion; Owing to lack flow-guiding structure, when leaking informaton, blower fan discharges air turbulence, produce very big noise pollution problem.
Summary of the invention: the purpose of this utility model provides a kind of blower fan tower airflow guiding device that leaks informaton, and solves mainly that place, the exhaust-duct exhaust noise that exists in the prior art is big, air-flow pours in down a chimney into blower fan and rainwater corrosive technical problem.The technical solution of the utility model is: a kind of blower fan tower airflow guiding device that leaks informaton is provided with multiple tracks and is folded to diaphragm in the exhaust-duct of tower silencing end of leaking informaton.Be folded to diaphragm by forming to chin spoiler with to baffle upper plate, to the length of chin spoiler is to the 2-3 of baffle upper plate length doubly, to the α of chin spoiler and horizontal sextant angle angle is 35 °-50 °, to chin spoiler with to the angle β of baffle upper plate angle is 90 °-100 °, being folded to the diaphragm spacing at 45-60mm, is 2/3 of the exhaust-duct degree of depth to the horizontal length of chin spoiler.The beneficial effects of the utility model are: to chin spoiler the air-flow that leaks informaton is played and cut apart regular effect, alleviated the noise problem of leaking informaton; Change the direction of the air-flow that leaks informaton to baffle upper plate, solved the problem of recharging air intake in the original design layout, improved the operational efficiency of gas blower; Owing to make progress, to chin spoiler length difference, solve rainwater and enter the etching problem that the tower sound damper that leaks informaton produces.
Description of drawings:
Fig. 1 arranges synoptic diagram for blower system
Fig. 2 is the utility model structural representation
Fig. 3 is folded to the diaphragm structural representation for the utility model
Among the figure: the 1-steam turbine; The 2-gas blower; The 3-tower that leaks informaton; The 4-tower sound damper that leaks informaton, 5-is to chin spoiler; 6-is to baffle upper plate; The leak informaton exhaust-duct of tower silencing end of 7-.
Embodiment: with reference to Fig. 1,2,3, gas-turbine 1 is arranged in a side of gas blower 2, gas blower 2 connects the tower 3 that leaks informaton by blowing line, the top of tower that leaks informaton is provided with the tower sound damper 4 that leaks informaton, the exhaust-duct 7 that air communication is crossed the tower silencing end that leaks informaton emits, and in the exhaust-duct of tower silencing end of leaking informaton multiple tracks is set and is folded to diaphragm.Be folded to diaphragm by forming to chin spoiler 5 with to baffle upper plate 6, to the length of chin spoiler 5 is to the 2-3 of baffle upper plate 6 length doubly, α angle to chin spoiler 5 and horizontal sextant angle is 35 °-50 °, to chin spoiler 5 with to the angle β of baffle upper plate 6 angle is 90 °-100 °, be folded to the diaphragm spacing at 45-60mm, the degree of depth (L) from the exhaust-duct to chin spoiler that insert is the 2/3L position.Being folded to diaphragm is steel plate, is welded by the steel plate of 4-10mm thickness, is fixed in the gas channel by welding process.
